The invention provides methods, compositions, and apparatus for performing sensitive detection of analytes, such as biological macromolecules and other analytes, by labeling a probe molecule with an up-converting label. The up-converting label absorbs radiation from an illumination source and emits radiation at one or more higher frequencies, providing enhanced signal-to-noise ratio and the essential elimination of background sample autofluorescence. The methods, compositions, and apparatus are suitable for the sensitive detection of multiple analytes and for various clinical and environmental sampling techniques.

The present invention relates to video recording and playback techniques and devices which create relative movement between a laser and an optical medium such as a flexible optical tape to permit the recording of different bandwidth signals. Further, the present invention relates to video recording and playback techniques and devices which optimize relative movement between a laser source and the optical medium in a cost-effective manner.

Method of storing digital video, audio and control information on an an

In a preferred embodiment, the invention relates to systems and methods for storing digital video information on an optical recording medium comprising the steps of moving the optical recording medium in a first direction, sinusoidally scanning a beam of light over the moving optical recording medium in a second direction substantially perpendicular to the first direction to establish a scan path over the optical recording medium, and periodically deflecting the sinusoidal scanning beam in the first direction to linearize at least a portion of the scan path. By linearizing at least a portion of the scan path, two traces can be made per cycle of a primary sinusoidal deflection, thereby doubling scanning efficiency.

A system for erasing data stored on an optical storage medium includes a housing, a guiding means mounted within the housing for guiding the optical recording medium on which the data is stored, and a heating means mounted in spaced-apart opposition to the guiding means for heating the optical recording medium to, thereby, thermally erase optical data stored on the medium.

A matrix-vector multiplication apparatus for performing a matrix operation at high speed and in a wide dynamic range, i.e., high precision, wherein an input vector is displayed with radiance of pixels, a display image is replicated into many images through an optical system. Component multiplications and partial summing between rows or columns of the matrix and the input vector are simultaneously performed by a light transmissive mask having transmitance proportional to one digit value of multi-scale (three or more) matrix component and a photosensor. Parallel channels each assigned to a different digit of the matrix component calculates the partial sums and a power-of-m (m is the number of scales) scaling summer connected to the parallel channels electrically produces components of an output vector.

An optical pattern extracting apparatus has sets of strip-like photodetection elements oriented in horizontal, vertical and diagonal directions for decomposing a displayed character to be recognized, the photodetection elements are distributed in a large number of parallel microimage channels generated through an optical image multiplication system and the photodetection elements cover a display area of the character without their photodetection areas overlapping each other.

In an image correlation calculation apparatus for optically calculating correlations between reference patterns and an image such as a character or any other figure, the image such as the character or any other figure subjected to correlation calculations is optically multiplied by a multiplier to form simultaneously in parallel a plurality of optical pattern images of a substantially identical shape, and optical correlation calculation between the plurality of optical pattern images and the reference patterns formed on various types of reference masks is performed individually and instantaneously, the various type of reference masks being arranged at a position spaced apart by a predetermined distance from the plurality of optical pattern image, thereby detecting beams emitted through the various types of reference masks. Image multiplication, optical correlation calculation, and transmission of the result of the optical correlation calculation to the photosensors can be simultaneously performed at a light propagation time. The apparatus structure can be simplified at low cost, and image correlation operations can be performed at high speed.
